Hydrostatic radial piston unit

A hydrostatic radial piston unit of the cam-lobe type of construction comprising a non-rotary shaft defining a rotational axis of the hydrostatic radial piston unit and extending with a front end region from a non-rotary, stationary rear casing to a rotary front casing, within the front casing a cylinder block is housed and fixed in a torque-proof connection to the front end region of the shaft, in the cylinder block radially reciprocating working pistons are disposed in radially oriented cylinder bores to and from which cylinder bores hydraulic fluid can be conducted by means of a distributor arranged rotationally fixed with respect to the front casing and rotationally free relative to the shaft, wherein a circumferential cam-lobe surface with which the working pistons can interact, is formed integrally with the front casing on its radial inner side, wherein a rear end portion of the rotary front casing is sealed by a seal against a front end portion of the stationary rear casing, wherein an axial position of the seal defines a sealing plane which is orthogonal to the rotational axis, and wherein the front casing is of a single piece design.
